Decontamination of a cannabis cultivation house

What if you rented your house to people who turned it into a cannabis cultivation site? What if you want to buy a house that has already been used for growing cannabis?

Houses that have been used to grow cannabis are often sold for less than their market value. However, it can be a good real estate opportunity if the decontamination work is carried out correctly. On the other hand, if the work is not done appropriately, this opportunity could quickly become your worst nightmare.

Plantation de cannabis au sous-sol nécessite une décontamination

Past cannabis cultivation in a house causes great damage because the humidity level maintained in these houses is very high and the ventilation is not optimal. The high humidity causes mold to grow and spores of mold to spread in the air. It is possible to completely decontaminate a house that has been used for growing cannabis using very rigorous techniques. This work often includes a lot of demolition. To make sure we solve the problem once and for all, we have developed a proven protocol over the years. Do not hesitate to entrust us with the decontamination of your home! In addition, our work is guaranteed.

Contact us before making an offer to purchase a property that has previously been used for cannabis cultivation. We will be happy to help you establish decontamination costs free of charge. All our managers and employees have training in mold decontamination and our company has the appropriate insurance to perform this type of work. If the work is done by a contractor who is not trained for this type of work your problem could come back in a few months. Always check your contractor’s certifications, this could save you a lot of time and money.
